| Abstract: | In this paper a modified method of preparation of 2,6-disubstituted benzo-1, 2-d;4,5-d']-bisoxazoles is reported.2,5-Diamino-quinone-1,4 was reduced with stannous chloride in hydrochloric acid. The product, 2,5-diamino-hydroquinone-l, 4 hydrochloride was then condensed with benzoic acid and substituted benzoic acids respectively in polyphos-phoric acid. Thus, 2,6-diphenyl benzo-1,2-d;4, 5-d']-bisoxazole and eleven of its substituted phenyl derivatives were prepared. |
